Leners Patent No. 87,592, maa Ma/rch 9,1869.

The 'Schedule referred to In these Letters Patentl and making part ofthe same.

To all to 'whom tlicsc presents shall come Be it known that I, REUBENRICH, Aof Dorchester, in the county of Norfolk, and State ofMassachusetts, have' made an invention of certain new and usefulIinprovenients in Tubular Wells; and do hereby declare the followingr tobe a full, clear, and vexact description thereof, due reference beinghad to the accompanying drawings, making part of this specification, andin which- Figure 1 isv a s ide elevation, and

Figure 2, a vertical and central section of a tubular well containing myimprovements;

Figures 3 and 4 being views ofthe scraper, andv Figures 5 and 6, viewsof the strainer to be described. This invention consists in combining,with the welltube, and' previous to,- as well as when such -tube isbeing driven into the. ground, a short metallic bar, which ills thelower part of such tube, and so as to cover the orifices made in it, theobject of this portion of the invention being to prevent admission ofsand, or other 1material into the tube, while driving it, as well as tocreate a vacuum in such pipe, the bar also serving, hy increasing`thefyweight of the tube, to facilitate its passage thronghthe earth, aswell as to strengthen -the tube.

In the drawings above mentioned as illustrating my invention, c denotesthe lower portion, or length of a cylindrical tube, now generallyemployed for tubular wells, suoli tube et heilig perforated, near itslower end,

with a series of oriices', D b l), 85e., for admission of.

water tothe interior of the tube.

To the lower extremity of the tube a is fitted a conical head, ordriving-point, c, seemed thereto in any propel' manner, such point beingcomposed of cast-iron, preferably in a chilled state.

-Within the lower part ofthe tube a, and resting upon the point c, is a'cylindrical block, or rod, d, ofsuch a diameter to ll the interior ofthe tube, and of suoli -a length as to cover its orifices b b1), theupper end of the said rod rl havingran eye, e, formed in'it, forconvenience of' removal. l

The cylindrical block fits tightly within the tube, and thus closes theorifices against the admission of dirt and sediment, while the tube isbeing driven, while, at the same time, it strengthens and stiffens thebody ot' the tube at the point where it is naturally the most weak.

After the` tube has been driven, the block is drawn Vup, by means of thecord, or other device which engages in the hole c, and, in its ascent,creates a partial vacuum, which induces and hastens the entrance of thewater.

The movable strainer' consists of acylinder or bag, f, of wire cloth,having secured to it one or more bails, or yolies, g, Ste., as shown inthe drawings, the bail, or yoke serving to. secure the cylinder' inplacel against compression, and asa handle for extracting it from orapplying it to the tube a. i g

Figs. 3 and4 of the drawings show an implement for cleaning thewell-tube of sand, or other extraneous matter which may have collectedtherein, such implement consisting of a metallic tube, g, havingasegment of its circumference cut away, and with its bottom inclined,with vrespect to the aperture tlnls formed, as shown in said gs. 3 and4, the cylinder being provided with a long handle, h, for operating it.

'As the natureof tubular wells, and the mode of ap'- plying or drivingthem is so well known, a description of` this process is not considerednccessai'y in this connection.

It might bewell to state, however, that previous to Ysubmerging theabove-described well, 4the bar-rod is to be dropped or forced into thelower part ofthe tube a.

After the tube has been driven to the proper depth, this rod is to beremoved by a suitable implement, and, if considered necessary, thestrainer before mentioned l applied in its place.

I n some soils, suchas coarse gravel, this strainer will not benecessary, while, in case of fine sand, its emlployinent will be foundadvantageous, if not absolutely necessary; hence my object in making itmovable.

It has been found, in practice,A that acast-iron point answers everypurpose of a steel one, and, in inauy cases, more durable.

Although, inthe accompanying draaizings, it is rep resented asalstraight cone, iu practiceit will be given a twisted form, in order tocause a rotation of it as it is driven downward.

' I claim the peculiar construction of the cleaning-implement, shown infigs. 3 and 4 of the accompanying drawings, when used in connection withtubular wells, for the purpose substantially as before set forth andexplained. i

Ialsp claim the employment, within the well-tube,

of the short metallic block or rod d, constructed and operatedsubstantially iii the manner and'for the purposes shown and described.
